The Blue Jays went with an eight-man bullpen out of spring training in part so that they wouldn’t have to expose right-hander Jeremy Jeffress to waivers, but they are already changing course.

Jeffress was designated for assignment this morning after he allowed a solo homer and two walks in one inning of work in his season debut last night against the Red Sox. Veteran right-hander Dave Bush has been called up from Triple-A Syracuse and will replace him in the bullpen. The Jays are expected to move back to a more traditional seven-man bullpen once Brett Lawrie is ready to return from his rib cage injury.

Jeffress throws hard, but his control has kept him from establishing himself on the big league level. The 25-year-old averaged 5.4 BB/9 in the minors and has issued 32 walks in 39 2/3 innings in the majors. While the Blue Jays would be happy if he passed through waivers unclaimed, somebody will likely take him on as a project.

Adam Wainwright tossed a spring-high 93 pitches in a Grapefruit League outing Tuesday afternoon against the Marlins and was declared the Cardinals’ Opening Night starter after the outing by manager Mike Matheny.
